Myopia
"Excimer-Lasik Laser Correction improves vision to the extent that the patient can go about his or her normal life without glasses or contact lenses".

Myopia is a type of refractive error of the eye.
Myopia occurs when light entering the eye is focused incorrectly, focusing images in front of the retina causing distant objects to appear blurry.
Excimer laser correction improves vision to the extent that the patient can live a normal life without glasses or contact lenses.
In this way, the discomforts caused by glasses (chronic irritation in nose and ears, weight of glasses, reflexes, limited peripheral vision, etc.) or contact lenses (intolerance for conjunctivitis or repetitive corneal ulcers, continuous requirement of careful care, high accumulated expense over the years, etc.) are avoided.
It also improves the physical aspect and achieves a higher quality of life and comfort to perform any type of activities.
What are the symptoms of myopia?
Poor distance vision will be the characteristic symptom, but two types of situations must be distinguished:
- Simple myopia: it constitutes a physiological variant of normality, which statistically is always logical to appear. This myopia does not usually exceed 6 diopters and is of limited evolution until 22 or 23 years.
- Pathological myopia, great, progressive or malignant: it is a pathological situation that is believed to be due to an alteration in the development of the posterior segment of the globe.
The most common symptoms are:
- Blurred distant vision.
- Eye fatigue.
- Headaches.
Do you have any of these symptoms?
You may be myopia
How is myopia diagnosed?
The diagnosis of myopia is made by means of a visual examination with which the visual acuity can be determined.
The ophthalmologist can determine the degree of myopia by means of a refraction test with which he can measure the eye's refractive power.
The magnitude of myopia is measured in negative diopters.
How is myopia treated?
Myopia can be corrected through glasses, excimer laser and intraocular lenses, which depending on the age and condition of the eye can be phakic (preserving the crystalline lens) or pseudo-phakic (replacing the crystalline lens with an intraocular lens).
The Excimer-Lasik and LASEK laser is applied to the cornea removing microscopic amounts of tissue to modify its previous curvature and correct the visual alteration.
The reason why the Excimer-Laser is used and not another instrument is because its extraordinary precision allows tuning beyond one thousandth of a millimeter (micron). In addition, the speed of the laser's action determines that the application time is ultra-short (seconds).
The characteristics of this operation are as follows:
- This technique is performed on an outpatient basis, that is, it does not require admission.
- It is performed under topical anesthesia (using drops and without the need for injection) so that no pain is experienced during surgery.
- It lasts about five minutes, of which the application of the laser is reduced to a few seconds, and the rest corresponds to the preparation of the patient.
